l Application led February 9, 1920r Serial No. 357,420.

To all whom it may concer-a: l Y Beit known that I, ROBERT W. WIEDER- wAx, a citizenV of thev United States, residing at `Atlantic City, in the county of Atlantic and State oi New 4Jersey, have invented certain newand useful Improvements in Heating Devices for the VVater- Circulation Systems of the Engines of Automobiles, of which Athe following is a specification.

This invention relates to improvements in heating devices for the water circulation systems of the enginesy of automobiles and the like.

An. important object of the invention is to provide a heating unit for use in connection 'with an automobile engine which may beY readily adapted` to all standard makes of' automobiles, without, in any manner altering the construction of thetengine.

A further objection of the inventionis to provide a heater which will cause the circulation of cooling water not only through the' radiator of theI engine, but within the engine water chamber.

A furtherobject' is to provide a heate 'of the type described4 which is so connected with the engine that it will ordinarily cause a circulation of heated water through bot-h the engine 4waterjvacket andk the Vradiator and which will, in event of the cold becoming so. severe as tocause freezing of the water in the small `tubes of the radiator, continueV to supplya circulation of heated water through the Ywaterjacket of: the enffine. A 1 D A further object is to provide a device of the above mentioned character which is readily andv cheaply constructed and the parts of which are readily interchangeable in the event oli-destruction in use.

Other objects and advantages' will become apparent.throughout the course of the following, discussion. Y j

In the accompanying drawings wherein for the purposes' ofillustration are shown preferredl embodiments of my invention,

Figure 1 Yis alongitudinal section taken through my apparatus.

'Figure 2 is a section on the line 22 of Figure 1.

Figurev 3 Figure 1. y

Figure 4t is a vtransverse section taken through my apparatus.

Figure 5 is a combined perspective showingr the wick casing and associated parts.

Referring now more particularly to the drawings, thenumeral 10 indicates a casing as awhole composed of a body section 11, and a head 12of double wall construction atliording a water chamber. The head 12 is connected with the chamber of the body portion 11 by means of spaced conduits 13.

The body portion 11 is provided with a connection 14 forming an inlet which may isa section on the line 3 3 of be connected by means of a suitable conv duit 15 with the water circulation system of the engine preferably at the lowest, or approximately the lowest, point thereof. The head 12 is provided with an outlet. y17 which is connected by a. conduit 18 with a point adjacent the upper. surface ot the head of the engine.

It will beobvious that water circulating through the. Casing is normally caused to pass from practically the entire length ot the headl of the engine thence through the radiator to its. lowermost point where it is again returned to the heater. lt will further he obvious that. with such circulation, it is impossible for the water in the waterjacket of the engine and practically impossible for that in the radiator to freeze, It will also be noted that in event of freezing of the water in the small pipes of; the radiator, thus `preventing theA circulation therethrough, this circulation will still be complete-,through the waterjacket of the engine. the inlet pipe thereto, the inlet pipe 15 oi the heater, the waterjacket of the heater and outlet pipe 18 connecting the heater and the waterjacket.

A wick casing 21 is provided having a broad rectangular base 22 which tapers upwardly to a narrow top, as at 23. The wick 24CV is composed of a plurality of seetions` of asbestos 25,-closely joined at their upper ends and expanded at their lower the casing is open, A perforated plate 32.

is provided havinga central longitudinal slot 33 formed therein., which receives the upper end of the wick casing'Ql.. Straps 34 are employed to hold the wick casing 21 and the plate 32 in position, the straps being secured in position by'means of bolts 35 or the like.

Slidably mounted upon the upper surface of the wick casing and wick is a member 36 embodying a bifurcated lower end 37 which straddles the upper end of the wick casing and provides a surface abutting the upper end of the wick. It will be obvious that bv shifting the member 36 from one end of the wick to the other, the lamekwill be extinguished. It will also be obvious that if the member 36 is shifted partially along the wick, as for example, to a point centrally thereof, but one-half of the wick will be burning. In this connection, it is to be noted that as a flame increases in length` it also increases in height, The member 36 therefore becomes a flame regulatorand extinguisher. v t

The upper end'of the member 36 is reduced as at 38 and has extending thereythrough a pin 39. This pin operates ina slot 40 formed in the lower end of the lever 41. .The upper end of the lever 41 has formed therein a slot'42 whichreceives a may be shifted longitudinally of the wick,

binding of the extinguisher or rod `being prevented by the slots in which the pins operate.

In order to provide for ready ignition of the wick, I have mounted in the wall of the casing 11, an insulating member 53, through which extends a conducting contact member 5,4 having Yone end arranged in proximity to lthe adjacent end of the wick casing 21. The

conducting member 54 is connected with a suitable wire 55' forming one terminal of a circuit, A wire 56 is provided forming the of thebody portion ll, through which extends one end of a pyrometer;

The lower edge of the outer wall of the head l2 is out-turned as at 61 and the upper edge of the outer wall of the body portion is out-turned as at 62, providing between their out-turned edges Ya gasoutlet space 63 through which the products oficombustion p' from the wick may escape. In order to prevent vagrant drafts from entering at the aperture and extinguishing the iame of the wick, I prefer to provide a shield 64 which surrounds the casing 10 at the aperture 63 and is held in spaced-relation thereto by means of supporting arms 65, as clearly shown in Figure 4. .Y Y

The; operation of this form of my apparatus 1s extremely simple and is thought to require no further explanation with the exception of fact that theattention is directed to the plate 32 which prevents back fire which may be caused by the explosion of gaseous fuels commonly present with automobile engines and which may be drawn into the heater by the draught caused by the flame, from communicatingtheir iame to Y other gaseous fuels without the heater.

As many changes are possible in the shape, size, and relation of the various parts here- 1n shown, I do not limit myself to the -specie structure herein before set forth, but may make any such changes without departing from thespirit of the-invention, or the scope of the subjoined claims. I

What I claim is: u 1. Awater heater'comprising a casing havlng spaced wallsforming 'a water chamber, the space within the inner walls forming a heating chamber, a burner arranged therein, va water head arranged above'V and spaced from said heating chamber, the outer wall of said casing and therwalls of said Vhead being extended toward each other andv spaced to permit passage of heated gases,`and con-` and nections between said vwater chamber said head. f I, 2. A water heater comprising a casing having spaced walls forming a water chamber, the space within the inner walls forming a heating chamber, a burner arranged therein, water head arranged above and spaced from said water chamber, the'outer walls of said casing and the walls of said water head being extended toward each other and outwardly, the adjacent edges'being spaced from each other to permit passage of heat-,

casing and the Walls of said Water head be- 10 -ing extended toward each other and outwardly, the adjacent edges being spaced from each other to permit passage of heating gases, connections between said Water head and said Water chamber, and a shield arl5 ranged adjacent said extended Walls.

In testimony whereof I afx in signature. ROBERT lV. VIEDERVAX.
